ANCHOR.

SPECIFICATION *forming part Of Letters Patent N0. 677,839, dat'ecl July2, 1901.

' Application filed February 16, 1901.' Serial No. 47,591. (No model.)

have invented certain new and useful Im-y provements in Anchors, ofwhich the following is a description, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

My invention relates to anchors for vessels; and its object is toprovide an anchor which shall be simple and inexpensive in constructionand while particularly adapted for use in muddy or soft bottom shallpossess great holding power when used on hard or rocky bottom and withwhich under whatever oircumstances used the cable cannot foul.

The principal features of my invention are a shank having a generallycylindrical shape having its lower end pointed, so as to readily sinkinto soft bottom by its own weight, and a substantially circular rim ordisk arranged on the shank at or near its upper end.

In the drawings, Figure 1 is a perspective view of my improved anchorinthe position which it assumes on hard or rockybottom. Fig. 2 is avertical sectional view of the anchor in the position which it assumeson soft or muddy bottom. Fig. 3 is a perspective view of a modified formof anchor in the position which it assumes on soft or muddy bottom, andFig. 4 is a vertical sectional view of a modified form of my anchorparticularly adapted for yachts and small vessels.

A is the shank of my anchor. This is preferably substantiallycylindrical for the main portion of its length. At its lower end ittapers to a point A. This shank is made of sufficientsize and weight tocause it to readily enter soft bottom by its own weight. In the formshown in Figs. l, 2, and 3 the shank carries near its upper end a rim ordisk B, preferably substantially circular in form. The diameter of thisrim or disk is prefer ably slightly less than one-half the length of theshank. Above the rim' or disk B the shank projects ashort distance, asshown at A2, and in the end of this portion A2 is se cured a ring C, towhich the cable is attached. The rim or disk B is preferably slightlythicker where it joins the shank than at its circumference, vits outeredge being sufficiently sharp to penetrate the thin layer of softmaterial commonly found on hard bottom or to engage any inequalitiesfound on such bottom. The rim or disk is preferably substantially atright angles to the axis ofthe shank.

In the modified form shown in Fig. 3 I prov vide the shank A near itspoint with ribs or dukes a, extending from the point Al upward a shortdistance along the shank and terminating at right angles to the axis ofthe shank. These ribs or iiukes aid in preventing the shank from beingpried out'of the mud which it has entered. In the same figure I show therim or disk B strengthened by providing it with longitudinal ribs at B',where it joins the shank A.

In Fig. 4 I have shown the rim or disk at the upper end of the shank. Bythus dispensing with the extension A2 and by securing the ring O in adepression C', formed in the upper face of the rim or disk B, the anchoris adapted to be conveniently carried on the deck of a vessel by simplyturning it point up, the flat vupper surface of the rim or disk Bresting flat upon the deck.

The shank and rim or disk B will in the case of anchors intended foryachts and vessels of small tonnage be conveniently made by casting itcomplete in one piece. In case of very heavy anchors it may be founddesirable to cast or otherwise form the shank and rim separately andunite them by any well-known method.

In use the anchor should,in muddy or sandy bottom, be droppedperpendicularly from the vessel, so that its point A' will enter the mudor sand by its own weight. As cable is then paid out the strain upon theanchor will be at substantially a right angle to the axis of the shankA, the shank acting as a stake. The tendency to pull' the shank out ofthe perpendicular will be resisted by the rim or disk B, which by reasonof its large surface will not be easily forced into the mud or sand.When the anchor is to be weighed, it will be readily withdrawn when thevessel is brought directly above it.

As the rim B presents no point for engagement of the cable, the cablecannot become fouled.

On hard bottom theprim or disk B will act IOO somewhat like the iukes ofan anchor of ordinary construction, the rim or disk being kept at aninclination to the surface of the bottom by the Weight of the shank.

Having thus described my invention, what I claim, and desire to secureby Letters Patent` is l. In an anchor, the combination of a shankpointed at its lower end, a rim or disk of a diameter less J[hanone-half the length of the shank near its upper end, and means forsecuring the cable to the upper end of the shank; substantially asdescribed.

2. In an anchor, the combination of a shank pointed at its lower end andprovided near its lower end with ribs or i'lukes extending along aportion of its length, a rim or disk of a diameter less than one-halfthe length of the shank near its upper end, and means for securing thecable to the upper end of the shank; substantially as described.

3. In an anchor, the combination of a shank pointed at its lower end, arim or disk of a diameter less than one-half the length of the' shank atthe upper end of the shank, a recess in the upper face of the rim ordisk and means for attaching the cable secured Within the recess andadapted to lie Within the recess when not in use; substantially asdescribed.

In testimony whereof I affix my signature in presence of two Witnesses.
